The PTB stands for Pourable Thick Bed. Good for floors, less so for walls unless you're Paul Daniels! I wouldnt use plywood either, I'd use plasterboard, Hardie or Marmox.
Beat me to it Rookery. I couldn't help but chuckle when i read it though.
What's the wall you're intending to batton onto made off exactly? Can you not board straight to it rather than framing and boarding?
Either way, i'd use plasterboard rather than ply as has been said, unskimmed its 32Kg. Miles cheaper than plying it.
